The phenomenon of vehicle park brake rollaway [PDF]

open access: yes, 2007
When a vehicle is parked on a slope with hot brakes, what appears to be a sufficient parking brake action can sometimes become insufficient. When the brakes cool down, the braking force reduces due to relaxation of the entire parking brake system, and ...

Thermal Brake Judder Investigations Using a High Speed Dynamometer [PDF]

open access: yes, 2008
This paper is concerned with addressing the problems experienced with the thermo-elastic behaviour of the disc - that of optimum heat dissipation, and equally important, even heating of the disc blade.

Optimisation of convective heat dissipation from ventilated brake discs [PDF]

open access: yes, 2009
Fast heat dissipation from brake discs is sought in current vehicles, where high power braking duties demand harmonic combination of strength, (undamped) disc mass and cooling abilities for a wide speed range.

Model Construction and Performance Degradation Characteristics of a Deflector Jet Pressure Servo Valve under the Condition of Oil Contamination

open access: yesInternational Journal of Aerospace Engineering, 2021
The deflector jet pressure servo valve is a kind of high-precision hydraulic component that can be widely used in the antiskid braking system of an aircraft. In actual service, it will be faced with extreme working conditions of gradual oil contamination,
